• The first digit defines the type of hydraulic circuit of the boiler sequence
• The second digit defines the type of burner or the type of burner control:
− Kx.1: 1-stage burner
− Kx.2: 2-stage burner
− Kx.3: Modulating burner with 3-position control
• For DC 0...10 V control of a modulating burner, the 1-stage burner is used as the
basic stage. In addition, a DC 0...10 V output must be assigned in the extra configu-
ration
• The plant type always applies to a boiler sequence
− with 2 boilers
− and using the same type of burner
Additional boilers, other types of burner, a heating circuit or a primary controller can
be configured in the extra configuration.
• The plant type activates function block "Boiler sequence manager" and function
blocks "Boiler 1" and "Boiler 2"
Basic type K; no preconfigured inputs and outputs
